FPGA implementation of low complexity crest factor reduction in OFDM systems

Orthogonal Frequency Division Multiplexing (OFDM) systems have a main drawback known as high Peak to Average Power Ratio (PAPR) or Crest Factor (CF). The main PAPR reduction techniques are Partial Transmit Sequence (PTS), Dummy Sequence Insertion (DSI), Selected Mapping (SLM), and the DSI-SLM. In th...
